fix(elysia): avoid AsyncLocalStorage probe on Bun

[adrian-scehura]

Avoid calling AsyncLocalStorage.enterWith(undefined) while detecting support on Bun because the probe replaces bun:test's active lifecycle context. Bun continues using its native implementation, while runtimes with missing or throwing implementations still receive the existing fallback.

Adds a regression test ensuring Bun detection does not invoke enterWith().

Closes #496

📝 Walkthrough

Walkthrough

The AsyncLocalStorage support check now skips the enterWith() capability probe on Bun. Other runtimes retain the existing probe. Tests cover the Bun behavior and restore stubbed globals after each test.

Changes

Bun AsyncLocalStorage fix

Layer / File(s)	Summary
Bun-specific capability guard packages/evlog/src/shared/asyncStorageScope.ts	Bun returns true without calling enterWith(). Other runtimes retain the existing validation and probe.
Regression test and release note packages/evlog/test/shared/asyncStorageScope.test.ts, .changeset/safe-context-probe.md	Tests verify that Bun does not invoke enterWith() and clean up stubbed globals. The changeset documents the patch.
Estimated code review effort: 2 (Simple)	~10 minutes
